Aerospace Center Defense (HARD) is a more challenging version of the Online Co-Op Mission Aerospace Center Defense, featured in Ace Combat Infinity. It takes place over Comona Base.

S Rank

As with other HARD Online Co-Op Missions, achieving an S Rank on Aerospace Center Defense (HARD) requires teamwork among all players. There will be difficulty in trying to earn the S rank with only 4 players.

One possible distribution of players would be to have at least two players for air-to-ground attack, at least one player for air-to-air attack, and at least one player for air-to-ship attack.

Debriefings

E or D Rank

While the enemy was prevented from obtaining it for themselves, the Space Station took considerable damage. We will have to struggle on without satellite surveillance until it can be repaired.

C or B Rank

The enemy forces have retreated, perhaps to avoid unnecessary losses. It is unlikely they have given up on the Space Center, but for now the operation is a success.

A Rank

The enemy forces have been driven off after sustaining major casualties. Damage to the Space Center was minimized, proving to the enemy that it will not be easy to outsmart our forces.

S Rank

Enemy forces on land, sea and air have all been destroyed.
Your attacks have prevented the Space Center from sustaining damage.

Trivia
